News of Instagram's revised terms of services agreement, which essentially allows the company to use your photos for advertising, have caused user backlash, but none so comical as the stir caused by Facebook CEO Mark Zuckerberg's sister.

Arielle Zuckerberg, who works for Google social-media marketing division Wildfire, hit her "Like" button today on an Instagram photo posted to Facebook by Instagram user and professional photographer Clayton Cubitt. The photo was a screenshot of a portion of the new terms of service, with a caption that read, "Instagram's suicide note."

The new terms, which take effect January 16, have been upsetting users since they were announced yesterday. The change comes three months after Facebook completed its acquisition of the popular photo-sharing site.
